Title: Resin-sealed semiconductor device
Inventor: OHIRO MASAHIKO
IPC: H01L21/52
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To support a semiconductor chip stably by supporting a die pad at four spots, in place of ordinary one-point supporting. SOLUTION: Since supporting spots for semiconductor chip 35 are four in number, and approach the end parts of the semiconductor chip 35. By forming four chip-supporting parts 34 of approximately the same height by press working using a lead frame as original material, so as to protrude from the exposed fundamental part 33 of a die pad 32, and supporting the semiconductor chip 35 by the supporting parts 34, a mounted posture of the semiconductor chip 35 is stabilizes, and a possibility of generation of inconvenience in a manufacturing process is diminished. Besides, the semiconductor chip 35 can be thinned, and consequently it becomes possible to thin a semiconductor device, since rigidity which is required by the semiconductor chip 35 becomes smaller by the increase of the supporting points.

Title: Quantization error reduction device for digital servo circuit
Inventor: TABUCHI JUNICHIRO
IPC: G05D13/62
Filed: 1990-11-15
Abstract: PURPOSE:To reduce the influence of the quantization error of the digital servo device by averaging several data of an error signal generated by a digital servo device and outputting the result as an error signal. CONSTITUTION:A microcomputer generates an error signal for rotation control over a capstan motor 10. For the purpose, an FG signal (signal from FG detector 12) from a capstan motor 10 is inputted to the microcomputer. Then the microcomputer is interrupted for input capture at the rise/fall timing of the FG signal (shaped by a waveform shaping circuit 11). Then the period of the FG signal is measured by this interruption operation to generate a speed error signal. A phase error signal is also generated similarly. The speed error signal and phase error signal are put together and the average of error signals of past two times is calculated and outputted as the error signal. Consequently, the quantization error of the digital servo device is reducible.

Abstract: PURPOSE:To keep the favorable interchangeability and commonality of a temperature-sensing element even when the thermal head concerned is downsized by a method wherein the temperature-sensing element is installed on the thermal head and, at the same time, a resistor, which is connected to the temperature- sensing element in series or parallel, is installed on the thermal head. CONSTITUTION:On a thermal head substrate 1, a plurality of driver ICs 3 for driving heat generating resistor train 2 and a temperature measuring thermistor 4 are installed. A circuit substrate 5 consists of an auxiliary substrate 6 and a flexible substrate 7, the terminal part 7a of which is connected under pressure to the terminal pattern part of the head substrate 1. On the circuit substrate 5, a resistor 8, which is connected to the thermistor 4 in series or parallel, is installed so as to connect to connectors 9.
